And unless you have another Mac you won’t be able to install the Mac software on your computer. You need OS 10.11 or higher.
I need to manually override a form which I understand can’t be done with the online version so assuming that is true I need to download the software.
Then on to my second post. Do you have a computer that will run the program?

What do you need to override? Maybe it can be done in the Online version.
I'm looking for the software. it's now too late to do online
@jmbarrs - The software to amend or the software to file?
Amended returns can only be mailed. It is suggested that it be mailed certified with return receipt (or other tracking service) to verify that the IRS receives it.
